To alla) hom t may concern.'

Beit known that we, GoRen H. SYLvEsfran and ANnnEw C. Sfnvrsrnn, citizens of the UnitedStates, residing at Cary Station, in the county of McHenry, State of illinois,

have invented' a new and useful Shovel, of

which the following is a specification.

This invention relates to scoop shovels, and more particularly to scoop shovels especially designedfor dredging lake or` river beds.

The primary object of the invention is to provide a shovel of this character wherein 17 of the rod 18,

the power' employed for inovii'igthe shovel through the surface being' dredged, may be utilized for dumpingtheshovel, eliminating the' necessity of. stopping' the machine yor power` device 'to accomplishthe dumping; result'.

Another object of the invention is t'o p rovidev means forV regulating the depth at which' the shovel may' work, adapting the shovellv for various uses'. v

A still furtherl object of theinvention is to"Y provide means from' dra'gfgiinp; material' saine vis being' 'returned'to its active or scoopine; position, by' floating' back when operatingin-water. l l

With the foregoing; and other objects in view which will appear as the description proceeds, the inventionv resides in 'the coinbiforv pr ev'entingv the shovel nat'ionand arrangement of parts and in the hereinafter described' and claimed, lit

being iunderstood that changes' inthe precise embodiment' of the inventionherein disclosed, nia'y' be Inade within the scope of what islclairned, without departing'frorn the sp'iritof thel invention.' Referring to the dra-wings: Y Figure'l is a side elevational view of the scooplin its active or scooping position.

Arms 10 are secured Io the end platesfo and extend forwardly therefronnthe arins-` providing' supports for the rod ll that sup-` ports the adjustable blade 12. a. The ends ofthe blad 12 are bentupwardly as atV 13 where they have `connectionl with the arr'ns lei that in turn are pivotally connected with the bars 15, as at 16. These bars '15 extend to points adjacent to the bar 6, where 'the saine are provided with openf ings to accommodate therightl angled-ends so that movement` of thev rod will resultl in a relative inover'n'entv ofthe' bars and blade associated therewith. Secured to one of the right ai'itile'd ends 17 isav keeper 19 adapted fto acconti". od'atea portion' of the lever ZO whi'chjispivotally supported" adjacent to thekeeper. Thusit will be seen that by'inovi'np;

shown by Figure l of the' dra'y'vi'ngs; rn'0'Ve- `rnent of the lever will produce arelative movement of thev bars 15 and rod 1S', tolthe end that the blade' supportedat the-- forward end ofthe shovel niayb'e'adjusted at tliewill ofthe operator.;

Y V

Associatedwith the guides 24 are pivoted latch rnernbers'l forlnedwith no'tclfedfporl tions 2S toaccorninodate the cables 25, one end o'f each of the latch rnenibers extending",v

, y beyondithe'b'arl assofc'iatedther'ewith to be drawings'in detail, the shovel includes a 'frame comprising" end' sec-` tions 5, whichj e'nd sections are" connected by' at`the upper ends thereof, the lower portions of 'the sec-V tions beine; coiniectedl'i-vV nieans of the bot confronted by the leversA 31. that are Divot' ally connected to thebars 21.

of each ofthebars 21. Y

adjacent to the e u ward edge of the hook members having connection with the ends of the cables 25 are are formed with openings the bolts 33 that extend through openings in the bars 34 so that the bars 34 may be adjusted with respect to their keepers to lengthen or shorten the dumping cables 35 that are connected to the poles 36. Thus it will be seen that due to this construction, oneof cned to cause the shovel to dig at a greater depth, at one side thereof rThe cables 35 also connect with the link 37, which link also has connection with the power cables 8 that extend over the ends of the pole 36 and' carry links 39 at their free ends. ffook members 40 are pivotally connected to the rod ll, each hook member including a pivoted section 4l formed with an extension 42 adapted to cooperate with the sliding latch member 43 to hold the pivoted section 4l associated therewith, in .its active position. When the latch member 43 is moved Afrom engagement with the extension 42, it is obvious that any pull directed to the At the upper keepers 32 which to accommodate hook members 40 will swing the sections 4l to their inactive positions to release the cables 38 and direct the pull of the power device; to the cables 35, causing theshovel to be tilted to its dumping position, as `clearly shown byFigure 2 of the drawings.

'Hingedly connected to the forward portion of the shovel, is a door 49 adapted to move to a position to partially close the forward end of theY shovel and prevent the shovel from dragging material with it,while the same is being sition.

lt is obvious that as the shovel is being drawn through the ground surface, the Inaterial passing into the shovel will cause. the door 49 to move to a position in proximity returned to a scooping po- `to the bottom 7 of the shovel.
